Great for older kitties

I have been using this product for about 2 years. Love the product. Don't like the fact that I can't get it in a 17 pound bag. Do you have any plans to make the product available in larger bags. Very expensive to buy multiple small bags.

Royal Canin response

I would be happy to make the suggestion for a larger bag!

Lifesaving

My himalayan Persian developed "mega colon" and came real close to dying. My vet got him cleaned out and now he is on this product along with Lactulose. So far so good and he has gained back much of the weight he lost when sick. The vet bills were extensive and this food isn't cheap but it saved his life!

A life saver

I adopted a sibling pair of 1 yr old female cats, unbeknownst to me one of them had megacolon. It took several months to show symptoms, but after an emergency vet visit and surgical deobstipation my vet recommended RC fiber response. It's been 18 months and Freckles is doing wonderfully, so well in fact that I was able to wean her off her meds. All 4 of my cats now eat RC fiber response exclusively.
My parents have a cat with hyperthyroidism and secondary IBS, he is now on RC fiber response and he has done amazing as well.

Wonderful to hear that they are all doing so well!

Cured my cat!

My cat couldn’t stop throwing up, every single day. We tried all kinds of foods, pills, and supplements, until the vet finally recommended this one. It immediately cured him. He is so calm and happy now, it’s like his personality came back now that he finally feels better. Just one side note: your cat will poo SO MUCH while on this food, but the nice thing is that it doesn’t stink!

Change in formula?

This food was pretty amazing. The only thing that helped my cat with his constipation problem. I also use it for my other cat since he has a history of urinary crystals. The only problem is that lately, they have had runny stools and what sounds like a lot of gas. Not sure if the formula was changes? They have been on this food for years and we never had this problem before.

I am so grateful our vet recommended this product , it literally has saved my cat's life. We had tried so many products and many trips to the vet to help Tigger with his bowels always getting bound up.After using this product less than a week he was doing great and has not had a reaccurance of issues.

Saved my cats life!

After 14 months of gastrointestinal problems, visits to two vets, expensive tests and several changes in medications and foods, my trusted vet suggested that I consider putting my little Annabelle down to save us both from the agony we had been going through. When I could not bear to make that decision without giving her one more chance, I drove a distance to a vet who specialized in cat care. That vet prescribed Royal Canin Gastrointestinal Fiber Response food, and I could not believe the difference it made in Annabelle's life! She is now a happy and playful and loving young cat. Thank you Royal Canin for giving my sweet cat a second chance and for literally saving her life!

Amazing health improvement

My poor cat was suffering from incredibly painful constipation. He is like a lot of cats- very finicky about his food and I was worried the transition would not go well. He loves this food and it has done wonders for his digestion. We are a happy family again.

Great Food That Works!

We brought in a stray cat that began hanging around our house -- you know the old story, feed a cat once... -- and when we took him to the vet, we found out he had digestion issues. Vet recommended this food, and literally, overnight, he changed. gone was his distress (bubble guts), diarrhea, and lack of appetite. Within a few weeks he was gaining weight and eating bowl after bowl. Cats love the taste, and it really works.
